Economic Impact Analysis for the Nitric Acid Manufacturing

Nitric acid is a water-soluble liquid that can range in color from clear to yellow and has a pungent acidic odor (Dow, 2008). Most of the chemical is used as weak, or industrial-grade, nitric acid and tends to range from a 50% to 70% concentration of nitric acid in water (Dow, 2008).

sorption in water to form nitric acid was first carried out in 1838 by C.F. Kuhlmann. However, this discovery was not then com-mercialised as ammonia was too expensive compared with the Chile saltpetre used to manufacture nitric acid in those days.

Nitric acid HNO3 PubChem

Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate. Nitric acid (HNO3).

What Is the Ostwald Process?

The first synthesis of nitric acid — by heating a mixture of saltpeter, copper sulfate and alum — is generally attributed to the Arabic alchemist Jabir ibn Hayyan Geber sometime in the 8th century, but there is some uncertainty about this. In the mid 17th century, the German chemist Johann Rudolf Glauber produced the acid by distilling saltpeter with sulfuric acid.

(57) Abstract: The present invention relates to a method for producing nitric acid in the range of 67 to 76% by weight by a single pressure method or a double pressure method. According to this method, the combustion of the ammonia used is carried out by compressed process air. According to the invention, process air is supplied externally for combustion and / or recovery.
